摘　　要：为了进一步改进热处理炉的温度控制系统,设计了以8031控制电路微处理器为核心的控制系统,首先给出了硬件设计,进行了2台电阻炉的温度系统、单片机炉温控制系统、温控模块、可控硅控制电路以及应用的温度设定电路拨码盘的设计,接着就2台加热炉的输入输出通道控制电路进行了设计,最后给出了系统的软件设计思路和相应的部分程序。结果显示:设计的温度控制系统具有精度高、测量误差小、稳定性好等优点。Abstract ：In order to improve heating furnace of temperature control system, 8031 circuit microprocessor of control system was designed. The hardware design was first given, then, the temperature system, single tablets machine temperature control system, temperature control module, and SCR control circuit were designed. Next, the appropriate part of the procedure was designed. The results show that the temperature control system has the advantage of high precision, little measurement error and high stabilitiy.
